sweet this works...gj on the tips
for a couple of weeks i had the problem, that extracted subtitles didn't show up. after browsing in here a bit i got an understanding of the problem and with a little more research and some trying i found a workaround for it. i already tried it a couple of times and it works for me.
1. download and unzip mkvtoolnix on your system
2. start a command line and browse to the folder
3. use the following command: mkvextract tracks "<Path>" 3:sub.***
> Example: mkvextract tracks "C:\Video.mkv" 3:sub.***
> Another Information: if the file has more than only one subtitle and you may want to extract another, open up the mkvtoolnix gui program ( called 'mmg.exe' ) and drag'n'drop the video file in it. what you're now looking for is the ID of the subtitle you want to extract. check out the window for 'tracks, chapters and tags' and search for the subtitle. if it's the id 4 you was looking for, use 'mkvextract tracks "C:\Video.mkv" 4:sub.***' instead.
4. when done you have your subtitle file. normally it should work, if the name is exactly of the video file, but it doesn't, so get Subtitle Workshop and install it
5. open up the program, load the subtitle and save it as it is as a "SubRip". the file will have the extension ".srt".
6. place the file in the same folder as the Video File and name it exactly alike.
> Example: "Video.mkv" and "Video.srt"
7. make sure no other files with the same name as the video file is at the folder and connect the usb/harddisk to the tv.
( 8. the subtitle might show up a bit to small, but via 'tools' and 'subtitle' on the remote control of your tv, you might enlarge it a bit. )
i hope this will help some users to get the wanted subtitles to show up. maybe this workaround may work for other systems, too, as there are no changes to the tv itself but only the video/subtitle file.
if you're beginners with the command line, copy this into an editor and save it as named. you should have unzipped the mkvtoolnix to the folder "C:\Program Files\mkvtoolnix" then.
cd C:\Program Files\mkvtoolnix
echo HOW TO:
echo 1. mkvextract tracks "<PATH>" 3:sub.***
echo 2. open subtitle workshop, load file and save as SubRip ( *.srt )
echo 3. copy subtitle file to video folder and rename it exactly alike
the script file ended above.
p.s.: if i find a way to implement those steps into one little program, i will edit this post with it.
